Claims.

My invention relates to cartons, and more particularly to a carton that is formed from a single blank of material suitably-scored or creased, and cut to provide the carton when it is folded. Cartons of this character are generally made of fibreboard or any other suitable paperlike or fibrous material which may be readily scored or creased, cut and perforated. v

My invention has as its objects, among others, the provision in a carton of the character described of an improved arrangement of walls and portions disengageable therefrom for enabling the carton to be readily and easily opened out to render access to the contents therein, in which the walls may be readily set up to form the carton, and which is of simple and economical construction. Other objects ofmy invention will become .apparent from a perusal of the following description thereof.

Referring to the drawings:

Fig. l is a plan view of my carton blank.

Fi 2 is an isome ric view of the folded blank which forms the ca on; the cover wall of the carton being shown partially disengaged.

Fig. 3 is an isometric view illustrating the carton almost completely unfolded. I

Fig. 4 is a fragmentary plan view of a modified form of construction,

hingedly connected together by parallel crease or score lines I. Hingedly connected to cover 3 adiacent the free edge thereof, by means of score or crease line 8, is a sealing flap 9 which'ls adapted to be secured to top wall 9 of the carton; the wall 9 being adjacent such edge in the folded position 1 of the carton illustrated in Fig. 2. For'securing Cartons of the character to which my invention relates are particularly adapted for the package ing of substances, such as ice cream, butter and' i cheese; and for these substances which are generally packed in the form of bricks, it is desirable that the carton may be readily opened from about the enclosed brick, so that the brick may be easily cut, or transferred to a dish or the like. The car- Y but with sealing flap 9 adhesively secured to top ton of my inventiomwhich' is designed to aecom I plish this, is formed from a single blank of material, preferably flbreboard, which may be easily scored, cut, or perforated, and which is illustrated in Fig.1; Such' carton is preferably employed without a liner. 2 Hence, theflbreboard is r preferably moisture-prooted by a suitable material, such as parafline. a

In the following description of the carton, the specific names applied to the walls are merely for purpose of'explanatiom. as it is tube understood,"for example, that any wall may be the bottom wall of the carton, although for clarity, only one wall is designated as the bottom wall herein. Such bottom wall 2 is formed integrally with a cover wall 9 which actually forms a side wall when the carton is positioned for opening thereof, as is illustrated in Fig. 2; another side wall 4; and a top wall 9. These walls are all sealing flap 9, a suitable adhesive, such as glue, indicated by the stippling II, is applied thereto. thus enabling it to be secured to the upper side of the edge portion of top wall 6 adjacent the sealing flap. 7

When the carton is set up, its ends :are closed by end closure flaps hingedly connected to the previously mentioned walls by means of transversely extending crease orsoore lines l2; the individual flaps being separated from each other in a conventional manner by means of longitudinally extending cut-s l3 which continue from the crease lines 1; Such flaps include rectangularly shaped flaps l4 integral with the top wall 6 and the bot tom wall 2, and locking flaps I6 integral with the cover 3 and side wall 4. Each of the looking flaps I6 is formed with a locking tongue I! and a partial cut l8 adjacent such tongue, to permit the flaps It at the same end of the carton. to be interlocked, as is depicted in Fig. 2, with the rectangularly shaped flaps ll overlapping inside the interlocked flaps. at such end; but anyv other con. ventional locking means can be employed.

It is the general practice to-ship the carton flat,

i. In filling the carton with'a substance such as ice cream, the carton is set up with the end flaps at their side closed; and after filling of the carton with the desired product, the flaps at the opposite end are then closed.

To enable the carton to be opened quickly, I provide 'a special arrangement of suitable lines of weakness, or tear lines in the carton blank,

which'may be formed by perforating the blank sheet; so that portions of thecarton may be readily disengaged. Such lines of weakness in-' clude parallel tear lines 2| in sealing flap 9,

cover 3 integral with tear strip 22 so as to be disengageable with the tear strip.

Top wall '8 is formed with parallel transversely extending tear lines 21, end portions of which coincide with tear lines 2| in sealing flap 9 when the sealing flap is secured to top wall 6; a 1ongitudinally extending out 28 being formed in top 8 between tear lines 21, to enable part 29 in the top and which is secured to sealing flap 9, when the carton is closed, to be readily removed with tear strip 22 when it is disengaged, as is shown in Fig. 2. The other disengageable part 3| in top 8 is integral with a disengageable part 32 in wall 4 formed by tear 1ines'33 in wall 4, which lead from tear lines 21 and extend obliquely to corners 34 adjacent the edge of bottom 2 opposite the edge of which comers 26 are located.

By virtue of the described arrangement. it can be seen from Figs. 2 and 3 that the carton can be readily opened by pulling on tab 23, to disengage tear strip 22 and portion 26' in cover 3. This leaves an opening 36 in top 6 rendering ready accessto part 3| in the top, which under pulling thereof will enable ready disengagement of the portion including part 3| and part 32.

' By virtue of the oblique tear lines 24 and 33 lead-.

ing to the four comers of bottom 2, the brick in the carton will be substantially completely exposed when the carton is opened. In this connection. it will be noted that the end portions of the carton will be secured only at such corners, as can be observed from Fig. 3. Consequently, they can be readily removed, either by a slight upward pull, or by bending them out of the way.

If desired, in order to facilitate handling 01 part 3| when it is desired to disengage it, the cut 28 between tear lines 21 may be formed to provide a tab 38, as shown in Fig. 4. This tab can be readily grasped after tear strip 22 is disengaged, since tearing of the strip 22 tends to lift the tab 38, thus minimizing the possibility of the hand contacting the contents in the carton. Also a spot of adhesive may be placed on the tab 38, or the portion of flap 9 adapted to overli the tab, so that as the tearstrip 22 pulls away from the tab 38, the tab will be lifted by virtue of the adhesive connection.
